Figure 6.

There were 14 points on each ellipsoid surface representing the diverse body size and shape combinations within each gender group (left: women; right: men). There were also two average models (one O for each gender). Four models for women (A, C, E, and G) were redundant to four models for men (B, D, F, and H). In addition, female model U was redundant to males model O; and male model W was redundant to female model O. The joint male and female enclosure space consists of 24 models which included 14 models for men (A, B, C, D, E, F, G, H, U, V, X, Y, Z, and O) and 10 models for women (B, D, F, H, V, W, X, Y, Z, and O).
